Hi everyone, I just need to get this off my chest. A few days ago, I injected Lantus (12 units) and must've hit a vein or something, because after 20 minutes I started feeling very dizzy, measured my blood sugar and was at 1.2 mmol/l, which is the lowest reading I've ever seen. I live alone for the most part, so there was no one to help, but I managed to drink a bunch of juice and eat some honey and my blood sugar slowly crept up. For 15 minutes or so I genuinely thought I was gonna die. Needless to say, I'm quite shaken by the experience. This has happened to me once before, about 2 years ago. For the moment, I'm measuring my BG 15-20 minutes after injecting Lantus so as to prevent any unpleasant surprises. Here's a disconcerting thought though - what if you accidentally inject bolus insulin into a vein? Does it get consumed and lower your BG within minutes or seconds, giving you essentially no warning? I'm also tagging @tim2000s as I recall he had lots of information on how Lantus works.
